nope, been there, 4 people in which i knew OP and other 3 were his friend and i use hardly for one month out of 12 months, why you wanna ask cause i hated the part to message him and then i could endless watch how many new thing are there and went to youtube. now i have stopped using yt too, so this shared email thing could solve this issue though, nice one OP, now regarding all can watch Netflix every 15-30 min will log out one member automatically so it could be a chaos for sure.
